摘要
以表面活性剂聚乙烯吡咯烷酮(PVP)为软模板,采用水合肼作还原剂还原钴盐制备出钴纳米棒,通过XRD、XPS、TEM等分析手段对其结构和形貌进行了表征。结果表明:这种方法制备出来的钴纳米棒长度约为3-4μm,直径约为70~100nm,具有hcp晶相和fcc晶相,其含量比例约为1:1。
Cobalt nanorods were synthesized by hydrazine reduction method using the macromolecule PVP as soft - template. The structure and the surface valency state of cobalt nanorods were measured by XRD, TEM and XPS respectively. The results showed that the cobalt nanorods consisted of both hcp and fcc phases, with the ratio of about 1 : 1. The cobalt nanorods were about 3-4μm in length and 70 - 100nm in diameter.
